In this paper, the quantum "synaptic" effect is studied that arises between two cold atom streams guided by cylindrical crossed wires carrying static (DC) and radio-frequency (RF) currents. The potential barrier between the two orthogonal atom streams is controlled electronically and atoms can be transferred from one wire to another under certain critical values of the wires' RF and DC currents and the biasing field. The results are interesting in the study of quantum interferometry and quantum registering of cold atoms.
